From a point 90 m from the foot of a tower, the angle of elevation of the top is 30 degrees. What is the height of the tower? (Take √3 = 1.73)
Answer and explanation
Correct answer: C. 51.9 m
- Step 1: Height = distance x tan 30 degrees = 90 x (1/√3).
- Step 2: Since 90/√3 = 30√3, the height is 30 x 1.73 = 51.9 m.
Answer
51.9 m.
